The Lowdown
Alright, let’s break down what’s coming for the next couple of weeks. The only spot in the mix is Tarnos - La Digue, a beach and jetty setup that’s exposed to the west and works best for beginners. The water is sitting at a warm 74°, which is much warmer than usual for this time of year, so that’s a nice bonus.
We’ve got a bit of a slow start, but the first real chance to get wet comes Sunday morning, September 6th. It’s glassy, with an easterly breeze, and the swell is a solid 5ft from the NW with a period of 12 seconds—that’s proper groundswell energy. The combined energy is up there at 661 (moderate-strong), and the conditions are looking clean. This is the standout of the whole window. The swell direction lines up nicely with the optimum, and with that offshore wind, it should be peeling nicely. Crowds are sometimes an issue here, so you might have a few friends out, but it’s worth it.
Sunday afternoon, the wind swings to the WNW at 15 km/h, turning cross-on and chopping things up. The swell drops a touch to 4ft, and the quality goes out the window. Not worth paddling out.
Monday the 7th and Tuesday the 8th are pretty marginal. Monday morning has a tiny 2ft swell with a very long 16-second period, but it’s onshore and messy. Tuesday sees a bit more size at 3ft, but again, the wind is onshore or cross-on, and the energy is weak to moderate.
Wednesday the 9th brings a bump in size—7ft from the NW—but the period is short at 8 seconds, and the wind is cross-shore in the morning, then cross-on and choppy in the afternoon. That’s a lot of water moving around for a beach break, and with the short period, it’ll be pretty lumpy. Not one for the average surfer.
Thursday the 10th looks better in the morning. Glassy conditions with a light ESE breeze, and a 5ft NW swell at 10 seconds. The energy is moderate (400), and the waves should be clean. This is a solid second option. The afternoon goes cross-on again, so get on it early.
Friday the 11th and Saturday the 12th are small. Friday morning has a 2ft NW swell with no wind—glassy but weak energy (90). Saturday morning is similar with 3ft and glassy, but the energy is only 112. Surfable, but nothing to get excited about.
Sunday the 13th morning brings a surprise: 2ft swell from the NW with a very long 13-second period, glassy, and the energy is decent at 234. The period is long enough to give some shape, but the size is tiny. It’s a fun little session if you’re on a log.
Monday the 14th morning is a good one. Offshore wind from the east, 4ft NW swell at 10 seconds, and clean conditions. The energy is moderate (296). This is another highlight, especially if you missed the Sunday morning session.
The rest of the second week is a mixed bag. Tuesday the 15th is onshore and poor. Wednesday the 16th morning is glassy again with a 4ft NW swell—clean but nothing special. Thursday the 17th morning has a 5ft NW swell, glassy, with strong energy (469). That’s a solid morning, but the afternoon goes cross-on and choppy.
From Friday the 18th through to the end of the window on the 21st, it’s mostly onshore or cross-on winds, with small to moderate swell. The energy stays low, and the conditions are ordinary. The 20th of September morning has a glassy, 3ft swell, but it’s weak.
Best bet: hit Sunday morning the 6th or Monday morning the 14th. Thursday morning the 17th is also worth a look if you’re free.
